Im having some problems with my engine that i can't figure out. My engine will be idling fine then all of sudden totally bog out and try to stall. Soo, i changed the fuel filter, dist cap is new, plug and wires are new, air filter is new, brought it in and got the timing worked on and got a hole blown through the cat convertor. I also got the fuel pressure taken and that was also good. Any ideas?
well in a 91' i would imagine that it is the same as my 89' which is an AMC 150. they are finicy*but mine seems to keep on kicking. it might poor gas qaulity or some gunk in your gas tank. i would try a variety of fuel additives, or maybe some injector cleaners (the gas additive kind).
yes, the 91 is a multi point fuel injection system.
retrieve the codes if any, and go from there.
there are also a lot of tests to be doe with various sensors etc. read the shop manual (haynes, chilton, etc) and go from there
